Tsuga Onsen

Tsuga Onsen is situated in Tsuga Town, Tochigi Prefecture, in the western Tochigi plain near the Watarase Reservoir — a major water management facility and important wetland bird sanctuary where migratory waterfowl gather in significant numbers along the Watarase River floodplain designated as a Ramsar Wetland of International Importance. The siliceous thermal waters here serve a rural farming community in western Tochigi where the natural wetland ecosystem of the Watarase basin, traditional agricultural landscapes, and local mineral spring resources combine to offer a quietly characterful countryside experience. Bathing at Tsuga Onsen in proximity to the Watarase wetland provides both therapeutic mineral spring relaxation and access to one of the Kanto region's most ecologically significant natural areas, where the combination of birdwatching culture, agricultural landscape, and siliceous hot spring bathing creates a distinctive western Tochigi wellness destination.
